Hey, I studied screenshots and game information to yesterday late night and I have it some ideas to your game concept.
1,
FleetsOn your mission can you go with one big ship, but you can do it with more smaller ships in fleet also. For piracy, stealth, thievery mission is better use fleet with small ships then use bigger ships. This is idea opens more options how to play and make this game a little more complex. Fleets will be unlock in middle game.

MiningI see we can trade missions, but I don't see anywhere mining or source gathering mission or room for that. I think some player do some this type of missions, you need workers, heavy machinery, droids, drills or mining lasers.

Science / ExplorationSpace is full of mysterious things, anomalies and places about we must explore and study to understood it (biological, physics and etc.). Will be nice more rooms and support for this mission type. Here is more place for tech trees where can develop some new version of rooms with small improvements for your ship.

Travel / ColonizationShip don't must carry only cargo, you can transport passengers or colonists to another word. Space taxi incoming ...
5,
Droids / Robots / AIIn the many sci-fi movies and games are droids or robots witch supstitude crew in in work or dangerous situation and I think will be nice here too. Droids are in some task more effective then people, but don't get experience and they are expensive.
Rooms Communication centre - Ship will be able to communicate with inner fleet ships and ships, bases and colonies at specific range.
Long range scanners - Ship will be to warn when another ship or any bigger object at specific range.
Short range scanners - Ship will be to warn when another ship or any bigger object and get detailed information about ship or object at specific range.
Mining laser - Ship will be able to mine of ore or another resources.
Drill - Ship will be able to mine of ore or another resources.
Corridors for machinery - Mode corridors, where can by use machinery for transport cargo with bigger width.
Hitch - Ship will be able to drag some object (small or big) in free space and move it to hangar or travel with it.
Engineer deck - Place where can be to repair damaged machinery or droids.
Passenger cabin - Ship will be able to carry passengers, this room can be in many levels of luxury for specific clients.
Laboratory - Place where can be to study biological entities or do biologic experiments.
Space laboratory - Place where can be to study space and physics experiments.
CrewWorkers - Man for manipulate with heavy machinery.
Scientist - Man for develop new technology or analysis space anomalies.
Infiltrator - Man for hacking and manipulating enemies droids, robots and AI.
Stay tuned, I will post some more my ideas little later ...
